This book is primarily intended for the Undergraduates and Post graduate students of Civil engineering.All Civil Engineering Structures (House Buildings, Departmental Complexes, Railways, highways, canals, flyovers etc.) are resting on the soil only. The safe design of such structures is of prime importance to ensure that these structures remain safe and free of undue settling and collapse. Therefore, Quantitative results of laboratory tests on soil samples are necessary to analyze the soil type, conditions etc.The book deals with soil laboratory testing procedures, as well as the collection and evaluation of test data. Moreover, the individual experiments introduced with its definition, concept and objective.Fourteen different soil tests are included in this book, with a single chapter devoted to each. All except a very few procedures follow those of the American Society for Testing and Materials ( ASTM) and/ or the American Association of State Highway and Transportation Officials (AASHTO).
